Michael Jackson isn’t the “King of Pop Art,” but an Andy Warhol portrait of the late singer netted $812,000 at auction last night.

The silk-screen image of Jacko was purchased by an anonymous bidder at Christie’s.

The painting was done in 1984, at the height of Jackson’s “Thriller”-era popularity.

It sold for a bit more than the $500,000 to $700,000 it was valued at, despite speculation that Jackson’s death would drive up the price.

“It was right about what we expected. We thought it was a great buy,” said Christie’s spokeswoman Amy Cappellazo.

“Even though that’s a kind of special celebrity image, in the end, the market is the market.”

Although the Jackson painting did OK, the two most expensive items — another Warhol, “Tunafish Disaster,” valued at $6 million to $8 million, and Jean-Michel Basquiat’s “Brother Sausage,” estimated to go for $9 million to $12 million — did not sell.

Overall, last night’s postwar and contemporary art sale at the Rockefeller Center auction house took in $74.1 million.
